BOTTLE CLOSURE.

Application filed November 16, 1922. Serial No. 601,273.

To all whom it may concern:

Be it known that I, FREDERICK G. SKULL, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements 1n Bottle Closures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to closures of the removable type which are employed for the purpose of sealing'receptacles containing liquid or dry ingredients.

A Well known form of removable seal employed more particularly in connection with glass receptacles embodies an outer seal ng capsule of aluminum having a rupturing tongue and a sealing flange crimped about the bead surrounding the mouth of the receptacle. This outer sealing capsule overlies an inner sealing disk of compressible material and a sheet metal disk interposed between the compressible disk and the sealing capsule. This form of closure provides a hermetically tight seal for the receptacle reserve the contents for an indefinite period and may be easily removed Without the employment of any special instrumentalities, the provision of the ru turing tongue permitting the outer capsu e to be torn off and the inner disks to be completely and easily removed from the receptacle. This form of closure, however, does not provide for rescaling the container after the ori inal seal has been removed therefrom. n many cases, such a rescaling feature is a desirable adjunct of a closure in order that foreign matter may be prevented from contaminating the contents during use.

It is accordingl the object of the present invention to prod uce a new and improved form of closure having all of the advantages of the form of closure above described and with the additional advantage of a resealing feature which may be employed after the removal of the original seal.

With this object in view the "feature of the invention contemplates the combination with an outer sealing capsule of thin sheet material havin a rupturing tongue and a dependingsealmg flange of an inner sealing disk of compressible material pressed against the mouth of the receptacle, and a secondary closure or seal interposed between the sealing disk and the outer capsule and having a substantially straight annular flange which projects downwardlyover the bead upon the receptacle a suficient distance to maintain the secondary seal and disk in place after the removal of the outer seal. Although the flange upon this secondary seal, as stated, is of sufficient length to maintain' the seal in place upon the mouth of the bottle, it terminatesshort of the base of the bead and is not crimped in and secured with the flange of the outer capsule.

In the accompanying drawings illustrat ing the preferred form of the invention Fig. 1 represents a section in elevation of the neck of the glass receptacle with the imroved form of closure applied thereto;

ig. 2 is a view similar to Fig. 1 illustrating the resealin portion of the closure with the outer capsu e removed; and Fig. 3 is a section in elevation of the closure before application to the receptacle.

The illustrated embodiment of the invention is applied to a glass receptacle or hottle having theusual neck portion indicated at 10 terminating in a round mouth portion surrounded by a sealing bead l2 and sealing recess 14. The closure, as indicated, comprises an outer sealing capsule 16 of aluminum or similar sheet material having an integral rupturing. tongue 18 and a depending sealing flange 20, which is crimped and bent along its lower edge 22 into the circumferential recess 14, as indicated clearly in Fig. 1; The outer sealing capsule overlies an inner disk 24 of compressible ma terial, which in turn is received within a secondary seal or capsule 26 having a relatively shorter depending flange 28, which fits closely about the head 12 and embraces a suflicient portion of the head to insure its retention upon the mouth of the bottle after'the outer capsulerhas been removed, as indicated clearly in Fig. 2. Upon the removal of the outer capsule by engagement of the ru turing tongue 18 and tearing of? the capsu e therewith, the inner or secondary capsule 26 is exposed and this capsule may be readily removed to permit the contents to be drawn from the receptacle. Thereafter the capsule may be replaced and constitutes a rescaling of the bottle which prevents the entrance of foreign matter outside of the receptacle. It will be evident to those skilled in the art that this resealing does not provide a hermetic seal for the contents but does serve as a simple and efiicient closure for the open mouth of the bottle, which does not interfere with the application of the original seal or its removal when the contents are to be used. From an inspection of Fig, 3, it will be noted that the sealing flange 20' upon the outer capsule is relatively longer than the flange upon the inner capsule and is designed to be crimped into the sealing recess atthe base of the bead 12 without causing a similar crimping action to be exerted upon the inner flange 28.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.

The invention having been described, what is claimed is: w I l y 1. The combination with a receptacle of glass or similar material provided with an annular bead adjacent the mouth, of inner and outer sealing capsules of thin sheet material, the outer capsule having a rupturing tongue and a sealin flange of sufiicient depth to extend complete y about the bead and be forced into a recess at the bottom thereof and the inner capsule having a straight sided annular flange of less depth fitting substantially closely about the bead and terminating short of the lower edge'of the outer sealing memes flange, whereby the inner'capsule is held onto the bottle irrespective of whether the outer capsule is applied or removed from the bottle, and a sealing disk of compressible material received and fitting within the inner capsule and compressed thereby against the edge of the bead surrounding the mouth of the receptacle.

2. The combination with a receptacle having an annular bead surrounding the mouth, of an outer capsule of thin sheet metal having a rupturing tongue in the upper portion and an annular sealing flange extending about the bead and pressed inwardly into engagement with the receptacle at the base of the bead, an inner capsule of thin sheet material having a relatively shorter annular flange fitting closely about the outer periphcry of the bead and directly engage said bead and terminating a sufiicient distance above the sealing flange to permit crimping of the outer sealing flange without a like crimping of the inner flange, but providing a sufiicient engaging surface with the bead of the bottle to hold the capsule on the bottle irrespective of whether the outer capsule is applied or removed, and a disk of compressible material received within'the inner capsule and compressed thereby against the surface surroundin the mouth of the receptacle, the inner capsule-together with the compressible disk serving to hermetically seal the receptacle when the outer capsule is in place and as a removable seal or closure after the outer capsule has been detached.
